Clickthrough URL automatically reformats to phone link??

When I attempt to add a clickthrough link to an image, Squarespace has begun reformatting the link in an adverse way. If the target URL contains a string of numbers in the URL, Squarespace automatically reformats the clickthrough link to be a phone link instead of a URL link. And, because a phone link cannot contain letters, Squarespace automatically deletes all of the letters in the URL link. This reformatting has the effect of preventing clickthrough links to a URL if the target URL contains a string of numbers.

So, for example, if the target URL in a clickthrough link is "../trip-reports/birch-bay-9-10-dec-2023" Squarespace reformats the clickthrough link to be a phone link to 9102023, the string of numbers that appear in the link. Squarespace refuses to link to the actual URL. There is no longer a way to generate a clickthrough link to a URL containing a string of numbers. Is there any way to turn off this adverse reformatting feature?
